Abstract

As a means of reducing the circumferential stress concentration in plates, the coaming plate around the edge of the hole to supplement the doubling plate is usually introduced. This paper deals with the effect of the coaming plate on the stress distribution in orthogonally aeolotropic plate under uniform tension. That is, we assume the coaming plate is a circular ring and by putting the edge stress of the plate [numerical formula], the problem can be solved theoretically and simply. In conclusion, the larger Yong's modulus of the coaming plate is, and the higher its height is, and the thicker its thickness is the more the circumferential stress is reduced.
